The invention is based on the object of creating a device for treating substrates with which a separation of processed substrates into one or more waste parts and at least one use is made possible. In particular, the invention is based on the object of creating a device for treating substrates which has improved flexibility.

This object is achieved by a device which is designed in accordance with the features of patent claim 1.

The advantages that can be achieved with the invention are that an effective and / or safe separation of substrates into at least one waste part and at least one Benefit is created while minimizing the mechanical effort required for this.
In one embodiment of the invention, it is particularly advantageous that the separating device treats substrate that has already been processed, in particular separates it into at least one waste part and at least one use, the substrate being processed by tool parts effective in the cylinder gap of two processing rollers upstream of the separating device, in particular by cutting, punching , Creasing or perforating. The functional stability of the device for treating substrates is increased by realizing the separation, also referred to as breaking, on the one hand, and the processing on the other hand at different locations. It is also particularly advantageous that the formation of two air supply means for the independent supply of first and second openings in connection with the ability to switch between suction air supply and a blown air supply ensures that waste parts and / or items are safely transported and released at the designated locations.

In the case of a device for treating substrates with a gripper system for fixing the front edges of sheet-shaped substrate, which is designed as a suction gripper system, it is particularly advantageous that substrate sheets or waste parts referred to as grids can be safely transported until they are released at the designated locations he follows. The suction gripper system has a comparatively simple structure in comparison to mechanical gripper systems, in particular clamping grippers. The design of the suction gripper system for transport in precise register can advantageously be omitted. In the case of the last-mentioned device, it is further particularly advantageous that the suction gripper system is assigned to the means for fixing the elevator, which includes the reverse case. This advantageously ensures that the number of moving parts is limited to a minimum. With a minimal footprint, the functions of fixing the elevator and holding the leading edges of the arcuate substrate and of Grids realized in a simple manner and also functionally stable. In a preferred embodiment of the invention, the suction air required to operate the suction gripper system is already present on the transport cylinder and can also be used in an advantageous manner to hold waste parts and / or items on the outer surface of the transport cylinder.

In an embodiment of the device for treating substrates with a separating device comprising a transport cylinder to which a circulating transport belt is assigned, it is advantageous, in particular, that the transport belt reliably takes over the waste parts or uses from the transport cylinder. If the conveyor belt is assigned directly to the transport cylinder and forms a transfer point or a transfer area with the transport cylinder, in particular in the form of a tangent point or a wrap angle, the conveyor belt can advantageously support the removal of the waste parts or use. The latter applies in particular when the conveyor belt is a suction belt. In the case of the last-mentioned device, it is also particularly advantageous that the transfer of waste parts or uses from the transport cylinder to the conveyor belt by applying blown air to the outer surface of the transport cylinder, i.e. is supported in particular at the openings of the elevator fixed on the transport cylinder. It is also advantageous if the transfer of waste parts or uses from the transport cylinder to the conveyor belt is effected solely by applying blown air to the outer surface of the transport cylinder and the conveyor belt does not have openings exposed to suction, i.e. is designed as a suction belt.

In the case of a device for treating substrates with a separating device, which comprises a transport cylinder and a break-out cylinder assigned to the transport cylinder, to which a circulating conveyor belt is assigned, there is an advantage in particular in the flexible usability of the device. If the conveyor belt is assigned directly to the stripping cylinder and forms a transfer point or one Transfer area with the stripping cylinder, in particular in the form of a tangent point or an angle of wrap, the conveyor belt can advantageously support the removal of the waste parts or use. The conveyor belt is assigned to the stripping cylinder, preferably in a contacting manner. The latter applies in particular when the conveyor belt is a suction belt. In the case of the last-mentioned device, it is also particularly advantageous that the transfer of waste parts or uses from the stripping cylinder to the conveyor belt is supported by the application of blown air to the outer surface of the stripping cylinder, ie in particular to the openings of the elevator fixed on the transport cylinder. It is also advantageous if the transfer of waste parts or benefits from the stripping cylinder to the conveyor belt is effected solely by applying blown air to the outer surface of the conveyor cylinder and the conveyor belt is not designed with openings subject to suction, ie as a suction belt.

According to a further embodiment, the separating device 2 is part of a substrate processing machine, in particular a sheet processing machine, and is operated inline with the units of the sheet processing machine. In particular, a sheet-fed printing machine is provided as the sheet-processing machine, as is shown in, for example Fig. 1 is shown. The invention is described below using the example of a sheet-fed printing machine, in particular an offset sheet-fed printing machine, this description is also intended to apply mutatis mutandis to other sheet-processing machines and to an embodiment of the device as an independent machine.
The sheet-fed printing machine includes a feed system for substrates 1, also referred to as feeder 7. Substrates 1 are understood to be, in particular, sheet-shaped workpieces made of paper, cardboard, cardboard, corrugated cardboard, plastic or the like, which are preferably printable or printed. The substrates 1 are present as a stack in the feeder 7 of the sheet-fed printing machine and are separated by the latter and fed to the units of the sheet-fed printing machine downstream of the feeder 7 via an acceleration system 8. The sheet-fed printing press comprises at least one, preferably several, printing units 6. The printing units 6 each include, in particular, a printing cylinder 41 and a sheet-guiding cylinder 42, preferably designed as a transfer drum 42. The printing cylinder 41 is assigned a blanket cylinder 43 carrying a blanket and this in turn a plate cylinder 44 carrying a printing plate. The plate cylinder 44 is in contact with an inking unit 45 and preferably also a dampening unit. In the printing unit 6, the substrate sheet 1 is guided in a known manner by the sheet holding systems provided on the printing cylinder 41 and sheet guide cylinder 42, printed in the nip formed between the printing cylinder 41 and blanket cylinder 43 and to the subsequent unit of the sheet-fed printing press, e.g. in the form of the next printing unit 6, passed. Following the printing unit or units 6 or between the printing units 6, one or more processing units 46 can be formed. The processing units 46 preferably comprise two processing cylinders 96, 97, one of which, preferably the lower one, has a sheet holding system and the other, preferably the upper one, has a tool carrier. The sheet holding system of the processing cylinder 96 can be designed as a clamping gripper system or as a suction gripper system. In its function and it is preferably identical to the gripper system (clamping gripper system or suction gripper system) of the transport cylinder 3, reference is made to the description thereof.

The processing cylinders are assigned to one another with the formation of a cylinder gap. At least one of the processing cylinders carries a tool. In the simplest case, a pair of processing cylinders is formed by the printing cylinder 41 and blanket cylinder 43 of a printing unit 6. In this case, a printing unit 6 serves as the processing unit 46. The clamping device for the rubber blanket is used in this case to fasten the tool on the rubber blanket cylinder 43.
The processing cylinders can be designed in a variety of ways.
According to an embodiment, which is particularly suitable for punching and perforating applications, the upper processing cylinder is designed as a full magnetic cylinder or carrier cylinder with magnetic segments for holding magnetic sheets or magnetic sheets and the lower processing cylinder as a surface-hardened cylinder or with a hardened sheet attached to it.
According to another embodiment, which is particularly suitable for embossing or creasing or grooving applications, the upper processing cylinder is a full magnetic cylinder or carrier cylinder with magnetic segments for holding magnetic sheets or magnetic sheets and the lower processing cylinder is a surface-hardened cylinder or with a hardened sheet attached to it or formed with a sheet of hard rubber / plastic.
The lower processing cylinder can be provided with tool carriers or elevator carriers that act mechanically, in particular positively or non-positively, in all of the cases mentioned. The force-fit tool carriers or elevator carriers are designed in particular to act magnetically.

According to a further preferred embodiment, the device for treating substrates 1, which can be designed as a sheet processing machine or can be part of the same, in particular a processing unit 46, comprises a first and a second processing cylinder 96, 97. Between the first and a second processing cylinder 96 , 97 substrate sheet 1 can be inserted, which at Passing through the cylinder gap between the processing cylinders 96, 97 are processed. The first processing cylinder 96 has a sheet holding system. The first and / or the second processing cylinder 96, 97 have a tool carrier for receiving a tool or a tool part, which preferably comes from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools. A counter-cylinder 98 is assigned to the second processing cylinder 97 on its side facing away from the first processing cylinder 96 and is in surface contact with the second processing cylinder 97.
The counter cylinder 98 is assigned to the processing cylinder 97 in such a way that when the processing cylinder 97 bends, as occurs when processing substrate sheet 1 in the gap between the two processing cylinders 96, 97, the force of the resulting bending force of the second processing cylinder 97 pushes the counter cylinder 98, preferably in its center or near its center. From a geometrical point of view, the centers of the first and second processing cylinders 96, 97 and of the counter cylinder 98 preferably lie on an imaginary straight line or the centers of the second processing cylinder 97 and the counter cylinder 98 lie on a straight line that is opposite to a straight line on which the center points of the first and of the second processing cylinder 96, 97 are inclined by an angle less than or equal to 10 degrees.
The counter cylinder 98 can have the same diameter as the second processing cylinder 97.
The counter-cylinder 98 and the second machining cylinder 97 can also have bearer rings that are in rolling contact with one another. It is also possible that the surface contact between the counter cylinder 98 and the second machining cylinder 97 is limited to the contact between the bearer rings. In this case, at least one deflection of the second processing cylinder 97 is counteracted in the areas between its bearing points in a frame wall and the bearer ring adjacent to the respective bearing point.

The use of bearer rings is known in printing machine construction. Bearer rings on printing machines are placed on the sides of the printing cylinders. The Schmitz ring should prevent Schmitz. It is made of tempered steel and is ground with high precision, round and true to size. The bearer ring is approx. 1-4 cm wide and rolls either on the foundation rail or on the bearer ring of the counter cylinder. The circumference of the bearer ring is exactly the circumference of the elevator or it has exactly the circumference of the shape, depending on which machine part it is attached to. The bearer ring is an element of positive control on printing machines with a central drive and compensates for minor bearing inaccuracies as well as uneven input and output from the gear drive of the printing machines.
In the case of the formation of bearer rings, a device for adjusting the pressure between the bearer rings by displacing the counter cylinder 98 and / or the second machining cylinder 97 is advantageously provided. A device for fixing an elevator is preferably assigned to the counter cylinder 98. This enables an elevator to be arranged on the counter-cylinder 98 to ensure that it is in surface contact, in particular rolling contact, with the machining cylinder 97 or with the tool arranged on its surface even when the tool is arranged on the second machining cylinder 97, the thickness of which can vary . A device for tensioning the elevator in the circumferential direction of the opposing cylinder 98 is preferably also assigned to the counter-cylinder 98, which device can form a structural unit with the device for fixing an elevator.
In particular for the use of a profiled elevator, for example in the form of a die, it has proven to be advantageous if the opposing cylinder 98 has a register system for positioning a elevator on the opposing cylinder 98.

For all the described embodiments with a film applicator or window applicator 85, it is useful if a turning device is arranged directly or indirectly in front of the plant in which the adhesive is applied. This has the advantage that, for example, for the production of envelopes, the cutting or punching lines or material tears as a result of the cutting or punching in the substrate 1 would occur on the inside of the envelopes, where they are less disturbing than on the outside.

In the following, a preferred method for treating sheet-shaped substrates 1 is described, which is based on one of the embodiments according to FIGS Figures 33 to 46 can be carried out.

The procedure is as follows.

In a punching process step, window-shaped areas are punched out in the substrates 1, material connections being retained. In a cutting process step, which preferably immediately follows the punching process step, the window-shaped regions are broken out of the substrates 1, the material connections being severed so that window-shaped cutouts are formed in the substrates 1. In a coating process step, which preferably immediately follows the separating process step, the substrates 1 are coated with adhesive in the adjacent area of the window-shaped recesses. In a window application step, film sections whose extension is greater than the extension of the window-shaped recesses are positioned over the window-shaped recesses and fixed with the adhesive.

In the case of the production of envelopes with windows, such a panel 10 would represent an unfolded envelope. After the window application, the substrates 1 are either placed directly on a stack or on a conveyor belt 29, 30; alternatively, the further material connections between the panels 10 or between the panels 10 and the waste parts 9, e.g. the outer frame, can be performed in a further separation process before being deposited , be severed. It is also possible to print the substrates 1 before the process step of punching. The method steps described are preferably carried out in consecutive units of a sheet-processing machine, in particular a rotary printing press.

Another embodiment relates to a method for treating sheet-shaped substrates 1.

The procedure is as follows.

A respective substrate sheet 1 is separated from a stack formed from substrate sheet 1 by a feeder 7, then embossed and / or dried in a first processing unit 46, then grooved or punched and / or punched in a second processing unit 46, then in a third processing unit 46 punched and / or punched and / or perforated and / or embossed and / or grooved. The respective substrate sheet 1 is preferably printed in one or more printing units 6 and / or coated in one or more coating units between the separation in the feeder 7 and the treatment in the first processing unit 46. As an alternative to this or in addition, the printing and / or painting in at least one printing or painting unit can also take place between the treatment in two of the processing units 46 and / or after the treatment in the last processing unit 46. After the separation, the sheet-shaped substrates 1 or panels 10 are preferably in one Display 99 or on a conveyor belt 29, 30 on a stack or as a result, placed in a scaly or unshifted manner.

Cutting is understood to mean, in particular, the complete mechanical separation of an unpunched material by pressure, with predominantly shear stresses acting. The cutting process can be done with knife cut, shear cut, or burst cut.

Punching is understood in particular to mean the dividing of materials in a dividing line that deviates from the straight line. The production of cutouts and blanks with self-contained delimiting lines is preferred. In some cases, however, open cuts are also made by punching, e.g. B. rounding corners and register punching.

Embossing is understood to mean the processing of materials by pressure with appropriate tools, the material being shaped and / or deformed in a relief-like manner.

Grooves are understood to mean the processing of materials by pressure with appropriate tools, with elongated, narrow indentations being made in the surface of the material.

Perforating is understood to mean the processing of materials by means of pressure with appropriate tools, a large number of mostly linearly arranged holes being made in the material. The distances between the holes are preferably the same.

To carry out the individual process steps of the described process, a separate work is preferably provided in each case, which can be used in any Sequence can be combined with other plants to implement modified production processes. For this purpose, the works preferably have their own frame walls. In particular, the method step of punching or the method steps of punching and separating is carried out with a punching unit, the method step separating with a separating unit 2.2, the method step coating with a coating unit 88.2, the method step window application or the method steps coating and window application with a window applicator 85. Each of the works mentioned, with the exception of the last work, transfers the substrate 1 to the following work after each at least one process step has been carried out.

Depending on the machine configuration implemented in each case, with or without a film applicator or window applicator 85, either substrate sheets 1 (copies 10 connected to one another via residual webs with or without frames) are available after going through various processing stages, which are stored in a display 99 in stacks or punched-out copies 10, which are preferably conveyed out of the machine on a conveyor belt 30. These utility 10 are preferably divided into utility streams which are laterally spaced from one another. For this purpose, several pairs of bugs are arranged following the conveyor belt 30, with each pair of rollers diverging from the other pairs of rollers, ie with a different lateral angular position. The roller pairs each form a roller gap and rotate at a circumferential speed that is greater than the speed of the conveyor belt 30. The adjacent and one behind the other benefits 10 are conveyed by the conveyor belt 30 into a respective roller gap. In the roller gap, the respective benefits 10 are then detected, accelerated to the circumferential speed of the rollers and spaced from one another in accordance with the alignment of the roller pair. The roller pairs are for Positioning on the benefit 10 transversely to its transport direction 74 displaceable. After the roller pairs, a conveyor belt is arranged that picks up the benefits 10, which are now laterally spaced from one another, and transports them away. The downstream conveyor belt preferably runs at a speed that is lower than the peripheral speed of the roller pairs.

The roller 83 or roller is arranged to be displaceable, for which purpose it is preferably mounted on levers at the end. If a gap is to be formed in the imbricated flow, because, for example, the stack carrier 78 has to be relocated or replaced, the roller 83 or roller is relocated or pivoted until it is in surface contact with the conveyor belt 29, 30. If the conveyor belt 29, 30 further conveys substrate sheets 1 as a result of its movement, these are accumulated on the roller 83 or roller. The roller 83 or roller can be mounted stationary or rotatable and in the latter case is preferably braked.

The transport device 79 is designed to move the stack carrier 78 in one or more positions in which the stack carrier 78 and the at least one stop 77 and / or the stack carrier 78 and the conveyor belt 29, 30 overlap. Preferably, several stops 77 are arranged transversely to the transport direction 74 of the substrate sheet 1 or the benefit 10 on the conveyor belt 29, 30 in groups next to one another. More preferably, each group of stops 77 has either two side stops or two side stops and one back stop. A group of stops in each case preferably forms a type of pocket which is aligned on the conveyor belt 29, 30 by positioning the stops 77 laterally on the stream or streams of substrate sheet 1 or sheet 10. The stops 77 are designed to be vertically movable. One or more drives are designed for the synchronous displacement of the stops 77. The transport device 79 preferably has a drive which is designed for the discontinuous or continuous displacement of the stack carrier 78. The transport device 79 is preferably designed to move the stack carrier 78 in and against the transport direction 74 of the transport belt 29, 30. The transport device 79 is further preferably designed to move the stack carrier 78 in the transport direction 74 of the transport belt 29, 30 depending on the extent of the substrates 1 or panels 10 in the transport direction 74 of the transport belt 29, 30. More preferably, the transport device 79 is designed to implement a movement cycle that comprises a first and at least one further movement of the stack carrier 78 in the transport direction 74 of the conveyor belt 29, 30, the stack carrier 78 between its first and its at least one further movement in relation to the transport direction 74 of the conveyor belt 29, 30 is stationary.
Furthermore, a feed device 80 can be formed with which at least one separating element 81 can be positioned on the substrates 1 carried by the stack carrier 78. The feed device 80 comprises a separating device which separates the separating elements 81 from a stack 82 formed from a plurality of separating elements 81. The separating elements 81 are preferably sheet-like materials that can be inserted between utility stacks for spatial separation of the same from one another. The feed device 80 can be formed by a horizontally displaceable frame, the underside of which is assigned vertically displaceable suction cups or other suitable fixing elements. The design of the feed device 80 with rigid suction cups or other suitable fixing organs is also possible, provided that the frame allows a vertical movement for lifting a respective separating element 81.
Preferred sequences of movements that the stack carrier 78 realizes by the action of the transport direction 74 are intended below in particular with reference to the Figures 20 to 32 are described by way of example.
First, the stack carrier 78 is positioned by the transport device 79 in relation to the transport belt 29, 30 in such a way that it is as small as possible from its underside in relation to its vertical position. In relation to its horizontal position, the positioning is carried out in such a way that copies 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the stack carrier 78. With the conveyor belt 29, 30 rotating, substrate sheets 1 or panels 10 are then conveyed onto the stack carrier 78 and are aligned laterally by the stops 77 and preferably also in the direction of transport 74. In the further course, the stack of substrate sheet 1 or panel 10 grows, as in FIG Figure 21 shown. The stack carrier 78 is preferably lowered. The stops 77 can also be lowered synchronously with the lowering movement of the stack carrier 78. Alternatively, the stack carrier 78 can also be positioned from the beginning at such a vertical distance from the conveyor belt 29, 30 that it can accommodate a sufficient amount of substrate sheet 1 or panels 10 without vertical movement. In Figure 21 only one stack can be seen. In addition to this, several other adjacent stacks can be formed at the same time. When the stack of substrate sheets 1 or panels 10 has reached a sufficient height, the stops 77, if these have been displaced with the stack carrier 78, are again displaced vertically into their starting position. The stack carrier 78 is vertically in its starting position and displaced horizontally by a distance which corresponds to the length of the substrate sheets 1 to be deposited plus a distance value. The time sequence of the displacement of the stack carrier 78 and the stops 77 is irrelevant, provided collisions are avoided. The shift is preferably carried out synchronously. During the displacement of the stack carrier 78, the device for forming a gap in the imbricated stream 83 is activated, so that during this time no substrate sheets 1 or copies 10 are fed to the stack carrier 78. After deactivating the device for forming a gap in the overlapping stream 83, the next stack of substrate sheets 1 or panels 10 can be formed on the stack carrier 78 ( Figure 24 ).

The processes are then repeated, as described for the formation of the first stack from substrate sheet 1 or panel 10, one or more times until another stack or further stacks are formed with the desired height, which, viewed in the transport direction 74, lie one behind the other and, if necessary, next to one another ( Figure 25 ).

At this point in the sequence, the feed device 80 can be used. This grips the uppermost separating element 81 of the stack 82 formed from separating elements 81 and transports it over the stacks of substrate sheet 1 or sheet 10 formed on the stack carrier 78, where it is released and is placed on the respective uppermost substrate sheet 1 or sheet 10 ( Figure 26 ). The surface of the separating sheet 81 takes the place of the surface of the stack carrier 78 in the further course and thus forms the new stack plane.

In a next step, a single or a series of stacks of substrate sheets 1 or panels 10 are formed on the new stack level. For this purpose, the stack carrier 78 is positioned in relation to its vertical position by the transport device 79 in such a way that the new stack plane lies below the release plane of the transport belt 29, 30. In relation to its horizontal position, the Positioning in such a way that copies 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the separating element 81. ( Fig. 28 With the circulating conveyor belt 29, 30, substrate sheets 1 or panels 10 are then conveyed onto the separating element 81 and are aligned laterally by the stops 77 and preferably also in the direction of transport 74. In the further course the stack of substrate sheet 1 or panel 10 grows as in FIG Figure 29 shown.
The stack carrier 78 is preferably lowered. The stops 77 can also be lowered synchronously with the lowering movement of the stack carrier 78. Alternatively, the stack carrier 78 can also be positioned from the beginning at such a vertical distance from the conveyor belt 29, 30 that it can accommodate a sufficient amount of substrate sheet 1 or panels 10 without vertical movement. When the stack of substrate sheets 1 or panels 10 has reached a sufficient height, the stops 77, if these have been displaced with the stack carrier 78, are again displaced vertically into their starting position. The stack carrier 78 is displaced vertically into the position it held at the beginning of the formation of the first stack on the separating element 81 and horizontally by a distance which corresponds to the length of the substrate sheets 1 to be deposited plus a distance value.
During the displacement of the stack carrier 78, the device for forming a gap in the imbricated stream 83 is activated, so that during this time no substrate sheets 1 or copies 10 are fed to the stack carrier 78. After deactivating the device for forming a gap in the overlapping stream 83, the next stack of substrate sheet 1 or use 10 can be formed on the separating element 81 ( Figure 31 ). If a sufficient number of stacks of substrate sheet 1 or panels 10 have been formed on the stack carrier 78, the loaded stack carrier 78 is transported away and replaced by a new stack carrier 78 capable of receiving it.

The sequence of the works of the sheet-fed printing machine results from the technological requirements. One or more processing units 46 are preferably formed following one or more printing units 6. In the case of several printing units 6, these are mostly equipped with different tools from the group of cutting tools, punching tools, creasing tools, perforating tools or grooving tools. One or more processing units 46 can also precede one or more printing units 6. Alternatively, one or more processing units 46 are interposed between one or more printing units 6. The sheet-fed printing press preferably also comprises one or more coating units, which are preferably connected downstream of the printing units 6 or are connected to the processing units 46.
A substrate-processing machine, in particular a sheet-processing machine that is not a printing machine, can have the same structure as the sheet-fed printing machine described, reduced by the printing units 6.
The separating device 2 is formed following the printing units 6 or the processing units 46. The separating device comprises a transport cylinder 3. The transport cylinder 3 is double-sized, ie it transports two substrate sheets 1 per revolution. However, the invention is not limited to a double-sized embodiment of the transport cylinder 3. The invention will now be described using a single-size system. This description is also representative of the double-size system or the multi-size system in analogous correspondence. In the area of the lateral surface of the transport cylinder 3, a sheet holding system for fixing the front edges of the sheet-shaped substrate 1, in particular a gripper system, is formed (in the case of a double-sized system, two sheet holding systems are formed). The gripper system is preferably designed as a suction gripper system 17, also referred to as a suction system 17, and is supplied by air supply means. The suction gripper system 17 is designed to generate a suction area, the extent of which in the axial direction of the transport cylinder 3 is a multiple of its extent in the circumferential direction. The extension of the suction area of the suction gripper system 17 in the circumferential direction of the transport cylinder 3 is preferably less than 20 mm, more preferably less than 15 mm, more preferably less than 10 mm. The suction area can be extended across the width of the Transport cylinder 3 extending opening or a plurality of adjacent suction openings be formed. The at least one suction opening is arranged for fixing the front edge of the substrate 1 in such a way that, when the elevator 5 is fixed, it is spaced apart from the elevator 5 in the circumferential direction of the transport cylinder 3. The extension of the suction area in the axial direction of the transport cylinder 3 is advantageously designed to be adjustable. For this purpose, setting means 28, in particular in the form of shut-off valves, can be provided in the supply path of the suction air for the suction openings which are outer with respect to the center of the transport cylinder 3. The adjustability of the extent of the suction area has the advantage that the consumption of suction air is minimized. The transport cylinder 3 further preferably has means (in the case of a double-sized system, two fixing means are formed) for fixing an exchangeable elevator 5. The means for fixing are preferably designed as clamping grippers. With them, a respective elevator 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the elevator 5 are preferably formed by the clamping element front edge 22 (also referred to as a clamping jaw) and the additional clamping element 24 (also referred to as a cuff) which interacts with this to form a clamping gap. The further clamping element 24 is firmly mounted on the base body of the transport cylinder 3. The clamping element 22 is firmly connected to a lever 21 which is mounted on the base body of the transport cylinder 3 such that it can pivot about a pivot point 34. The lever 21 is tensioned by an energy storage device 23, preferably designed as a spring, such that the clamping gap formed between the clamping element 22 and the further clamping element 24 closes. The spring 23 is designed as a compression spring and is supported with one end on the lever 21 and with its other end on the head of a screw screwed into the base body of the transport cylinder 3. The Figure 3 shows the front edge of the clamping gripper with the front edge of the elevator 5 fixed, ie in the closed state. The Figure 4 shows the front edge of the clamping gripper with the front edge of the elevator 5 released, ie in the open state. The opening of the front edge of the clamping gripper is effected against the force of the spring 23. The one to open the clamping gripper The force required at the front edge is preferably applied by an adjusting element 23, which can in particular be designed as a pneumatic muscle 23. The adjusting element or the pneumatic muscle 23 preferably acts on a further lever 33, one end of which is supported on a fixed point of the transport cylinder 3. Under the force of the actuating element 23, which can in particular be designed as a pneumatic muscle 23, the further lever 33 can be pivoted about the aforementioned fixed point. In the case of the formation as a pneumatic muscle 23, this is acted upon by compressed air, under the action of which it expands, the further lever 33 being pivoted. The pivoting movement of the further lever 33 is limited by a wall formed on the transport cylinder 3. The further lever 33 acts on a ball 35 which is formed between the further lever 33 and the lever 21 and displaces it. With the displacement of the ball 35, the lever 21 and with it the clamping element front edge 22 are also displaced. If the actuating element 23 is actuated in the opposite direction, or the pneumatic muscle 23 is depressurized, ie switched to a powerless state, the force of the energy accumulator 23, in particular the spring 23, the lever 21, the ball 35 and the further lever 33 shifts again in the direction of it Starting position until the movement is limited by hitting the front edge 22 of the clamp element against the front edge 24 of the clamp element or the elevator 5. The rear edge of the elevator 5 can be fixed between a clamping element rear edge 47 and a further clamping element rear edge 48, which together form a further clamping gap. The force required to close the rear edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the rear edge 47 clamping element via a toggle lever 51. To tension the elevator 5, at least one of the clamping grippers, ie the clamping gripper front edge or the clamping gripper rear edge, can be displaced in the circumferential direction of the transport cylinder. In the Figures 3 and 4th the rear edge of the clamping gripper can be moved. In particular, the rear edge of the clamping gripper is mounted on a slide that is displaceable in the circumferential direction of the transport cylinder 3. In addition to the rear edge of the clamping gripper, the carriage 49 also carries the tensioning shaft 50 and the Toggle lever 51. To tension the elevator 5, it is first fixed at both ends by the front edge of the clamping gripper and the rear edge by the clamping gripper. The slide 49 is then moved clockwise, which is effected by a further adjusting element 52, which can also be designed as a pneumatic muscle. Regardless of the type of design of the means for fixing the elevator 5, these preferably carry positioning pins or are preferably assigned positioning elements. The positioning pins or positioning elements can in particular be assigned directly to the further clamping element front edge 22.
The transport cylinder 3 preferably has first and second openings 12, 13 which, when the elevator 5 is fixed, are at least partially covered by the openings that can be formed in the elevator 5. The openings 12, 13 are connected to air supply means 14, 15. In particular, first air supply means 14 for supplying the first openings 12 with air and second air supply means 15 for supplying the second openings 13 with air are provided. In the following context, air is understood to mean all forms of system air, ie in particular blown air or suction air, which are particularly suitable for exerting a physical effect such as force and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. In particular, the chemical composition of the air or its moisture content is irrelevant. Such air is generated in a manner known per se with compressors, compressors, vacuum pumps, suction pumps or similar components. The aforementioned air generators can comprise the first and second air supply means 14, 15 of the transport cylinder and in particular form the air supply means 14, 15 together with all means that supply the air to the openings 12, 14 and / or control the supply.
The first and second openings 12, 13 can preferably be supplied with air independently of one another. The air supply to either the first or the second openings 14, 15 or both openings 14, 15 is preferably designed to be switchable. In this sense, switchability is in particular switching meant between suction air and blown air, whereby it does not matter which type of air supply is switched to which type.
The first and the second openings 12, 13 are formed in the lateral surface of the transport cylinder 3. The first and second openings 12, 13 are preferably arranged alternately in the circumferential direction of the transport cylinder 3 or in the axial direction of the transport cylinder 3. The first and / or the second openings 12, 13 are preferably designed in the form of grooves or holes. The arrangement of the first and second openings 12, 13 in the outer surface of the transport cylinder 3 preferably results in a fine-meshed network of elements with which any openings formed in the elevator 5 can be supplied with air. The arrangement of the openings in the elevator 5 takes place in accordance with the arrangement of waste part or waste parts 9 on the one hand and benefit 10 on the other. For example, in the area of those first openings 12 that are formed in the area of panels, perforations can be formed in the elevator 5, while none of the second openings 13 that are formed in the area of panels 10 face any perforations in the elevator 5. The same applies accordingly to the area of waste parts 9, the second openings 13 being opposite openings in the elevator 5, while the first openings 12 are covered by closed areas of the elevator 5. As a result of these measures, use 10 and waste parts 9 can be treated differently or fixed on the outer surface of the transport cylinder 3 or its elevator 5.
The details of the air supply to the first and second openings 12, 13 are in particular in FIGS Figures 5 , 6 and 7th shown. The air supply means 14, 15 for supplying the first and second openings 12, 13 preferably comprise one or more rotary slides or rotary inlets. The rotary slides or rotary inlets are preferably formed on the end face of the transport cylinder 3 or assigned to it. Preferably two rotary slides or two rotary inlets are formed on opposite end faces of the transport cylinder 3. In the in the Figures 5 , 6 and 7th The example shown includes the rotary valve or the at least a rotary lead-in a disk 18 which is assigned to one of the end faces of the transport cylinder 3. Several groove-shaped recesses 19, 56, 57 are formed in the disk 18, which preferably extend in the shape of a segment of a circle, coaxially to the axis of rotation 16 of the transport cylinder 3. The recess 19 is supplied with air via a first supply connection 53, the recess 56 via a second supply connection 54 and the recess 57 via a third supply connection 55. The recesses 19, 56 and 57 are formed on the side of the disk 18 facing the transport cylinder 3. They extend in different radii in the shape of a circular segment, coaxially to the axis of rotation 16 of the transport cylinder 3.Each of the recesses 19, 56 and 57 does not have to be continuous in the circumferential direction of the disk 18, but rather can be perforated, so that several viewed in the circumferential direction of the disk 18 on the same radius Form recesses 19, 56 and 57 lying one behind the other. The recesses 19, 56 and 57 correspond in terms of their distance (radius) to the axis of rotation 16 of the transport cylinder 3 with openings 58 formed in the end face of the transport cylinder 3. Each of the openings 58 in the end face of the transport cylinder 3 communicates via further lines either with a single or a part of the first openings 12 or with a single or a part of the second openings 13 in the lateral surface of the transport cylinder 3 or with the suction gripper system 17. This of course only applies as long as the respective opening of the respective recess 19, 56 and 57 depending on the angular position of the Transport cylinder 3 is opposite. At the in Fig. 2 The illustrated embodiment supply the recesses 57 closest to the axis of rotation 16 of the transport cylinder 3, the suction gripper system 17, the recesses 56 adjacent to these second openings 13 and the recesses 19 adjacent to these the first openings 12.
The disk 18 stands still with respect to the transport cylinder 3, which rotates about the axis of rotation 16 in the operating state. The extension of the recesses 19, 56 and 57 in the circumferential direction of the transport cylinder 3 creates areas of suction or blown air determined, which are formed on the outer surface of the transport cylinder 3 relative to the angle of rotation.
Superimposed on these effects, the areas of suction or blown air can also be determined by the type of air supply or by its connection or disconnection. The area supplied in its extension by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can thus be shortened by switching off the air supply at an angle. Likewise, an area supplied in its extension by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blowing air supply. The suction area on the outer surface of the transport cylinder 3 is used for fixing and the blowing area for pushing off benefits 10 or waste parts 9. It goes without saying that the air supply for the first openings 12 is preferably independent of the air supply for the second openings 13.
According to a preferred embodiment, the first and / or the second air supply means 14, 15 are designed to switch off the suction air supply or to switch between suction air supply and blown air supply depending on the angular position of the respectively supplied openings 12, 13. The first air supply means 14 preferably switch the air supply to the first openings 12 off or from the suction air supply to the blowing air supply when the respective first openings 12 reach a first release point by rotating the transport cylinder 3 about its axis of rotation 16. More preferably, the second air supply means 15 switch the air supply to the second openings 13 off or from the suction air supply to the blown air supply when the respective second openings 13 reach a second release point by rotating the transport cylinder 3 about its axis of rotation 16. The disk 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the transport cylinder 3. The transport cylinder 3 is preferably rotatably mounted in the same frame on which the torque arm 20 is articulated.
To shift the areas of suction or blown air that are formed on the outer surface of the transport cylinder 3 in relation to the angle of rotation, adjusting elements for rotating the disk 18 can be provided.
In order to facilitate assembly, the disk 18 preferably has a recess which enables a radial displacement of the disk 18 in the sense of a displacement for the purpose of replacement.
Instead of one disk 18, several disks 18 can also be provided. In the case of several disks 18, the recesses 57 for supplying the suction gripper system 17 are formed in one of the disks 18, and the recesses 19 and 56 for supplying the first and second openings 12, 13 in the other disk 18.
The details of the supply of the suction gripper system 17 are in a preferred variant in Figure 8 shown. In the exemplary embodiment shown, the disk 18 serves to supply the first and second openings 12, 13 and to supply the suction gripper system 17. '
As an alternative to this, the disk 18 can also exclusively have a groove-shaped recess 57, which preferably extends in the shape of a segment of a circle, coaxially to the axis of rotation 16 of the transport cylinder 3. In this embodiment, too, the recess 57 is supplied with air from a third supply port 55. The recess 57 is formed on the side of the disk 18 facing the transport cylinder 3. The recess 57 is preferably continuous or interrupted in the circumferential direction of the disk 18, so that a plurality of recesses 57 or sections of the recess 57 lying one behind the other as viewed in the circumferential direction of the disk 18 are formed. The recess 57 corresponds in terms of its distance (radius) to the axis of rotation 16 of the transport cylinder 3 with one or more openings 58 formed in the end face of the transport cylinder 3. The or each opening 58 communicates via further lines with the suction gripper system 17 respective opening 58 of the recess 57 depending on the angular position of the transport cylinder 3 is opposite. In other words, the length and the position of the angular region in which suction air is applied to the suction gripper system 17, ie the suction gripper system 17 has a holding effect, is determined by the extent and position of the recesses 57.
It goes without saying that the air supply to the suction gripper system 17 is not limited to the described embodiment with disks 18. The air supply of the suction gripper system 17 can also be implemented with other known embodiments of an air supply, which can activate and deactivate the suction air applied to the suction gripper system 17 in cycles with sufficient speed.
The suction gripper system 17 is formed in the area of the lateral surface of the transport cylinder 3. The suction gripper system 17 is preferably assigned to the means for fixing the elevator 5. In particular, the suction gripper system 17 can be mounted on the means for fixing the elevator 5. Preferably, the means for fixing the elevator 5 itself and thus also the suction gripper system 17 are movably, in particular pivotably, mounted. The suction gripper system 17 can in particular be assigned to the clamping element front edge 22. It is also advantageous to arrange the suction gripper system 17 together with the clamping element 22 on the lever 21.
According to a preferred embodiment, a break-out cylinder 4 is arranged adjacent to the transport cylinder 3. The stripping cylinder 4 is rotatably mounted like the transport cylinder 3. The break-out cylinder 4 is used to break out waste parts 9 or items 10. The break-out cylinder 4 preferably has third openings 32. Third air supply means are provided for supplying the third openings 32 with air.
Like the transport cylinder 3, the break-out cylinder 4 can also be double-sized or single-sized. In the case of a double-sized design of the stripping cylinder 4, its circumference or diameter corresponds to the circumference or diameter of a double-sized transport cylinder 3 Stripping cylinder 4 is of a single size. The structure of the stripping cylinder 4 is preferably similar in many features to the transport cylinder 3, so that reference is made to the explanations regarding the structure of the transport cylinder 3 to describe the nature of the stripping cylinder 4. This applies in particular to all assemblies of the transport cylinder 3 or of the break-out cylinder 4 for which there is no explicit reference to structural differences or a lack. The nature of the stripping cylinder 4 is described below using a single-sized system. This description is also representative of the double-size system or the multi-size system in analogous correspondence. In contrast to the transport cylinder 3, the stripping cylinder 4 does not have a sheet holding system for fixing the front edges of the sheet-like substrate 1. Like the transport cylinder 3, the stripping cylinder 4 preferably has means for fixing an exchangeable elevator 5. The means for fixing are preferably designed as clamping grippers. With them, a respective elevator 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the elevator 5 are preferably formed by the clamping element front edge 22 and the further clamping element 24 which interacts with this in relation to form a clamping gap. The front edge 22 of the clamping element is mounted on the base body of the stripping cylinder 4. The further clamping element 24 can in particular be formed as a leaf spring package. An adjusting element 25, preferably designed as a pneumatic muscle, is arranged adjacent to the further clamping element 24. The adjusting element is preferably connected to an air supply with which an overpressure can be applied to the adjusting element 25. When an overpressure is applied, the adjusting element 25 expands, in which case it rests against the further clamping element 24 and deforms it. As a result of the deformation, in particular the bending of the further clamping element 24, its extension changes in the direction of the clamping element front edge 22 Shutdown of the overpressure on the actuator 25 can be reduced, what the Terminating the elevator 5 corresponds. The Figure 10 shows the clamping gripper of the stripping cylinder 4 front edge with the front edge of the elevator 5 fixed, ie in the closed state.
The rear edge of the elevator 5 can be fixed between a clamping element rear edge 47 and a further clamping element rear edge 48, which together form a further clamping gap. The force required for closing the rear edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the rear edge 47 clamping element via a toggle lever 51.

For tensioning the elevator 5, at least one of the clamping grippers, that is, the clamping gripper front edge or the clamping gripper rear edge, can be displaced in the circumferential direction of the stripping cylinder 4. In the Figure 10 the rear edge of the clamping gripper can be moved. In particular, the rear edge of the clamping gripper is mounted on a slide 49 that is displaceable in the circumferential direction of the stripping cylinder 4. In addition to the clamping gripper rear edge, the carriage 49 preferably also carries the tensioning shaft 50 and the toggle lever 51. To tension the elevator 5, it is first fixed at both ends by the clamping gripper front edge and the clamping gripper rear edge. The slide 49 is then displaced counterclockwise, which is effected by a further adjusting element 52, which can also be designed as a pneumatic muscle.
Regardless of the type of design of the means for fixing the elevator 5, these preferably carry positioning pins or are preferably assigned positioning elements. The positioning pins or positioning elements can in particular be assigned directly to the further clamping element front edge 22.
It goes without saying that the elements described for fixing the front edge and the elements for fixing the rear edge can also be designed in a different manner. As an alternative to the formation of non-positively acting elements, it is also advantageous if the elements for fixing the The front edge and / or the elements for fixing the rear edge are designed for the form-fitting fixing of elevators 5. In this case, hook-shaped or claw-shaped holding elements can in particular be formed, which correspond to recesses that are formed in the elevator 5 or engage in holding rails that are firmly connected to the elevator 5.
The clamping gripper front edge or the clamping gripper rear edge are preferably mounted in a channel of the stripping cylinder 4, which can be spanned by a channel cover.
The stripping cylinder 4 preferably has third openings 32 which, when the elevator 5 is fixed, are at least partially covered by the openings that can be formed in the elevator 5. The third openings 32 are connected to third air supply means. In the following context, air is understood to mean all forms of system air, ie in particular blown air or suction air, which are particularly suitable for exerting a physical effect such as force and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. Such air is generated in a manner known per se with compressors, compressors, vacuum pumps, suction pumps or similar components.
The third openings 32 can be supplied with suction air. The air supply is preferably designed to be switchable. In this sense, switchability means, in particular, switching between suction air and blowing air, whereby it does not matter which type of air supply is switched to which type. The third openings 32 are formed in the lateral surface of the stripping cylinder 4. The third openings 32 are preferably embodied in the form of grooves or holes. The arrangement of third openings 32 in the lateral surface of the stripping cylinder 4 preferably results in a fine-meshed network of elements with which any openings formed in the elevator 5 can be supplied with air. The arrangement of the openings in the elevator 5 takes place in accordance with the arrangement of the waste part or waste parts 9 on the one hand or use 10 on the other hand. For example, in the area of those third openings 32 which are formed in the area of use Openings are formed in the elevator 5. This proves to be advantageous if the stripping cylinder 4 is to be used to transport the panels 10.
If the break-out cylinder 4 is to be used for transporting waste parts 9, openings are preferably formed in the elevator 5 in the area of those third openings 32 which are formed in the area of waste parts 9. By means of these measures, benefits 10 and waste parts 9 can be treated differently or fixed on the outer surface of the transport cylinder 3 or its elevator 5. The release of the benefits 10 or waste parts 9 can be supported by applying blown air to the third openings 32.
The details of the air supply to the third openings 32 are not shown separately and are described below with reference to the design of the air supply means 14, 15 on the transport cylinder 3. The air supply means for supplying the third openings 32 preferably comprise a rotary valve or a rotary inlet. The rotary slide valve or the rotary inlets are preferably formed on the end face of the transport cylinder 3 or assigned to it. The rotary slide valve or the at least one rotary inlet preferably comprises a disk 18 which is assigned to one of the end faces of the break-out cylinder 4. A recess X is formed in the disk 18, which preferably extends in the shape of a segment of a circle, coaxially to the axis of rotation of the stripping cylinder 4. The recess is supplied with air via a fourth feed connection 53. The recess is formed on the side of the disk 18 facing the break-out cylinder 4. The recesses are not continuous in the circumferential direction of the disk 18, but rather can be perforated, so that several recesses lying one behind the other as viewed in the circumferential direction of the disk 18 are formed on the same radius. Each recess corresponds in terms of its distance (radius) to the axis of rotation of the stripping cylinder 4 with openings 58 formed in the face of the stripping cylinder 4. Each of the openings 58 in the face of the transport cylinder 3 communicates via further lines either with a single or a part or all of the third openings 32 in the lateral surface of the stripping cylinder 4. Of course, this only applies as long as the respective Opening 58 of the respective recess depending on the angular position of the break-out cylinder 4 is opposite.
The disk 18 stands still with respect to the break-out cylinder 4, which rotates around its central axis in the operating state. The extent of the recesses in the circumferential direction of the stripping cylinder 4 defines areas of suction or blowing air that are formed on the lateral surface of the stripping cylinder 4 in relation to the angle of rotation.
Superimposed on these effects, the areas of suction or blown air can also be determined by the type of air supply or by its connection or disconnection. Thus, the area supplied by the third air supply means corresponding to the recess can be shortened in that the air supply is switched off in relation to the angle. Likewise, an area supplied in its extension by the third air supply means corresponding to the recesses can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blowing air supply. The suction area on the lateral surface of the stripping cylinder 4 is used for fixing and the blowing area for pushing off benefits 10 or waste parts 9.
According to a preferred embodiment, the third air supply means are designed to switch off the suction air supply or to switch between suction air supply and blown air supply depending on the angular position of the respectively supplied third openings 32. The third air supply means preferably switch the air supply to the third openings 32 off or from the suction air supply to the blown air supply when the respective third openings 32 reach a third release point by rotating the breakaway cylinder 4 about its central axis. The disk 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the stripping cylinder 4. The break-out cylinder 4 is preferably rotatably mounted in the same frame on which the torque support 20 is articulated.

In order to shift the areas of suction or blown air that are formed on the lateral surface of the stripping cylinder 4 in relation to the angle of rotation, adjusting elements for rotating the disk 18 can be provided.
In order to facilitate assembly, the disk 18 preferably has a recess which enables a radial displacement of the disk 18 in the sense of a displacement for the purpose of replacement. The recess has an extension which is greater than the diameter of a pin of the stripping cylinder 4 in the region of the stripping cylinder 4 in which the disk 18 is assigned to it.
The stripping cylinder 4 and the transport cylinder 3 carry for the treatment of substrates 1, in particular for separating or breaking out processed, ie cut or cut web-affixed or perforated substrate 1 into at least one waste part 9 and at least one use 10, preferably one elevator 5 each or breaking out, remaining retaining webs or material connections or material connections that are not intended to be completely cut through, in particular fibers or fiber bundles, are torn in the area of cutting lines between waste part 9 and at least one panel 10. For this purpose, one of the elevators 5 can be designed as a die and the other elevator 5 as a male mold. The patrix has a base plane and areas that are raised in relation to the base plane. The raised areas act on the substrate 1 and form tools. The die has a base level and areas or further recesses that are recessed in relation to the base level. The die and the male mold are arranged on the transport cylinder 3 or the stripping cylinder 4 in such a way that the raised areas of the male mold are opposite the recessed regions or the further recesses of the female mold. The male part forms a kind of counterpart to the female part. The die is arranged either on the transport cylinder 3 or the stripping cylinder 4 and the male die is arranged on the other cylinder. The other cylinder in this sense is the cylinder that interacts with the cylinder carrying the die (transport cylinder 3 or break-out cylinder 4). The die is preferably arranged on the transport cylinder 3 and the male die on the stripping cylinder. The The male and female tool pair described above preferably differs from male and female tool pairs as they are used in cutting or perforating, for example on the machining cylinders upstream of the separating device 2. The structural design of the male mold is determined by its function of only pressing the elements to be separated or broken out into the recessed areas or the further recesses of the female mold. Accordingly, the raised areas of the male mold can also have significantly smaller extensions than the recessed areas or further recesses of the female mold that correspond to them. In particular, a flexographic printing plate can be used as the male mold.
In an alternative embodiment, the male mold does not have any areas that are raised in relation to the base plane, but rather a base plane that is raised as a whole. In this case, the male part is provided with an elastic coating or formed from an elastic material, at least on the side facing the female part.
When separating or breaking out waste parts 9 and use 10 are moved relative to one another, with residual webs or individual fibers or fiber bundles being torn in the area of cutting lines. For this purpose, either the waste parts 9 or the benefits 10 are preferably pressed by the male mold into the recessed areas or the further recesses of the female mold. In the case of using a male mold with an elastic surface, the waste parts 9 are pressed into the recessed areas or the further recesses of the female mold, the surface of the male mold expanding at these points, while in areas of the surface outside the recesses or further recesses in the the die, the substrate is pressed against the surface of the die.
According to a further preferred embodiment, the transport cylinder 3 is not assigned a break-out cylinder 4, with the waste parts 9 and benefits 10 also being moved relative to one another in this embodiment and residual webs or individual fibers or fiber bundles being torn in the area of cutting lines. The separating device 2 is preferably designed such that it acts exclusively on the side of the processed substrate 1 facing the transport cylinder 3, while the substrate 1 is on the Transport cylinder 3 is transported. In a preferred embodiment, the separating device 2 is formed from raised areas and areas of the surface of the transport cylinder 3 that are recessed in relation to the raised areas. First openings 12, which can be in operative connection with first air supply means 14, are furthermore preferably assigned to the recessed areas. The first air supply means 14 are preferably designed to supply suction air. More preferably, an elevator 5 is interchangeably assigned to the outer surface of the transport cylinder 3, the raised areas of the surface of the transport cylinder 3 through the elevator 5 and the recessed areas of the surface of the transport cylinder 3 through the outer surface of the transport cylinder 3 in the area of openings formed in the elevator 5 are formed. In the raised areas and / or the recessed areas of the surface of the transport cylinder 3, second openings 13 can be formed which are in operative connection with second air supply means 15. Furthermore, the first and / or the second air supply means 14, 15 can be switched between a suction air supply and a blown air supply. To realize the relative movement of the waste parts 9 and benefits 10 relative to one another, the transport cylinder 3 can be assigned an elevator 5, which is designed in particular in the manner of a die and has recessed areas or further openings. In the area of the recessed areas or further openings, a negative pressure is applied via the first and / or second openings 12, 13, which moves the waste parts 9 and panels 10 relative to one another, i.e. in particular pulls the waste parts 9 into the recessed areas or the further openings , while the benefits 10 are supported on the base plane of the die. As an alternative to this, provision can also be made for the panels 10 to be drawn into the recessed areas or the further openings, while the waste parts 9 are supported on the base plane of the die. In other words, the separating process is preferably brought about solely by the force of the negative pressure applied in the recessed areas or further openings or the suction air on the sides of the utility 10 or waste parts 9 facing the transport cylinder 3. In the area of the recessed areas are preferred Arranged openings. These ensure that the negative pressure applied to the first and / or second openings 12, 13 can spread to the side of benefits 10 or waste parts 9 facing the transport cylinder 3.

When the substrate sheet 1 is separated into waste parts 9 and use 10, problems arise in particular in environments with low humidity, which are caused by undesired electrostatic charges on waste parts 9 and / or use 10 and / or the surfaces of transport cylinder 3 and / or break-out cylinder 4. As a result of the electrostatic charges, waste parts 9 and / or benefits 10 adhere to the surfaces of transport cylinder 3 and / or stripping cylinder 4. In these cases, the effect of gravity is usually not sufficient to remove waste parts 9 and / or benefits 10 from the cylinder surface, or to remove from the tools or tool parts, in particular male and female molds, fixed on the cylinder surfaces.

According to a further embodiment, which serves in particular to avoid problems caused by electrostatic charges, provision is made to design a separating device 2 which comprises a transport cylinder 3 and a break-out cylinder 4 assigned to it, an antistatic device 95 being assigned to the transport cylinder 3 and / or the break-out cylinder 4 is ( Figure 9 and Figure 49 , with the Figure 49 the transport cylinder 3 is shown as an example). The transport cylinder 3 preferably has means for fixing an exchangeable elevator 5, as well as openings 12, 13 which, when the elevator 5 is fixed, are at least partially covered by openings that can be formed in the elevator 5, air supply means 14, 15 for supplying the openings 12, 13 with air are provided. The antistatic device 95 preferably includes at least one electrode connected to at least one high voltage source. The high voltage source can be a positive or negative high voltage source. Alternatively, the high-voltage source can be switched between an operating mode as a positive and an operating mode as a negative high-voltage source. The high voltage sources can have a The controller can be connected to a sensor which detects the voltage applied to the surfaces of the transport cylinder 3 and / or the stripping cylinder 4 or the tools or tool parts attached to them. The controller is preferably designed to activate the positive or negative high-voltage source or to switch the convertible high-voltage source as a function of the sign of the applied voltage. The controller can also read the value of the current Fig. 12 Process voltage as a system parameter and control at least one high voltage source depending on this system parameter. The high-voltage sources described preferably supply a pulsed or an unpulsed DC voltage.
The electrode of the antistatic device 95 preferably extends in the axial direction of the break-out cylinder 4 over its length and / or in the axial direction of the transport cylinder 3 over its length.
According to a development, the antistatic device 95 comprises a brush, the brush comprising a roller-shaped or a strip-shaped base body, which is designed in particular to be electrically conductive. Bristles 105 are assigned to the base body. The base body can be rotatably mounted in the case of a cylindrical design.
In this case, the bristles 105 are preferably evenly distributed on the outer surface of the base body. In the case of a strip-shaped design of the base body, it is fixedly arranged at least in one operating position with respect to the surface of the cylinder to which it is assigned (transport cylinder 3 or break-out cylinder 4).
The bristles 105 are preferably formed from an electrically conductive material such as metal. A carbon compound can also be used as the material of the bristles 105. The bristles 105 are more preferably formed from interwoven fibers or fiber bundles. These can be arranged in a row next to one another. Preferably there are several of those described Rows of interwoven fibers or fiber bundles, viewed in the direction of rotation of the transport cylinder 3 or stripping cylinder 4, are arranged one behind the other. As an alternative to the assignment of bristles 105, a cloth 105, which has electrically conductive fibers, can also be assigned to the base body. The fibers can be woven into the cloth 105 or connected to the cloth 105, for example by means of an adhesion promoter. In the further developments in which bristles 105 or a cloth 105 are assigned to the base body, the bristles 105 or the cloth 105 form the electrode or are connected to the electrode.
The embodiments of antistatic devices 95, which are equipped with bristles 105 or a cloth 105, are arranged in relation to the transport cylinder 3 or break-out cylinder 4 in such a way that they touch the outer surface of the respective cylinder. A device is preferably provided with which the antistatic device 95 between an operating position in which the bristles 105 or the cloth 105 touch the surface of the respective cylinder and a parking position in which the bristles 105 or the cloth 105 do not touch the surface of the respective cylinder touch, is relocatable.

Furthermore or as an alternative to this, it is preferred in such developments that the antistatic device 95 comprises a blowing device which generates a volume flow of a gaseous medium ionized by at least one electrode in the direction of the outer surface of the transport cylinder 3 and / or the outer surface of the break-out cylinder 4.

As an alternative or in addition to the design of the separating device 2 with an antistatic device 95, the tools or tool parts used, such as the die and male mold, and / or the cylinder surfaces of the transport cylinder 3 and / or a break-out cylinder 4 assigned to it, can also be antistatic, in particular with electrically conductive materials, be formed.

According to another preferred embodiment, with or without a break-out cylinder 4, a circulating conveyor belt 29 is assigned to the transport cylinder 3, as shown in particular in FIG Fig. 11 or Fig. 12 . can be seen. The transport belt 29 is preferably arranged above the transport cylinder 3. The transport belt 29 is assigned to the transport cylinder 3, preferably wrapping around part of the circumference, forming a wrap angle. As an alternative to this, the conveyor belt 29 can also be assigned to the conveyor cylinder 3 with the formation of a tangent point 36. More preferably, the tangent point 36 is formed in the 12 o'clock position of the transport cylinder 3. The length of the conveyor belt 29 is determined by the arrangement of pulleys. The conveyor belt 29 preferably has a horizontally extending transport area 37. The conveyor belt 29 can in particular be designed as a suction belt. More preferably, suction air is applied to the conveyor belt 29 at least in the transport area 37. It follows from this that the conveyor belt 29 can be designed for suspended transport of items and / or waste parts 10, 9. The conveyor belt 29 in particular has the function of processed substrate sheets 1, waste parts 9 or benefits 10 at the tangent point 36 or in the area of the wrapping around the conveyor belt 29 in order to take over the transport cylinder 3 therefrom and to transport it further.
Another transport system, for example in the form of a further transport belt 30, can be connected to the transport belt 29. An overlap area is preferably formed between the conveyor belt 29 and the further conveyor belt 30, in which the processed substrate sheets 1 or panels 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30. Further preferably, the further conveyor belt 30 is designed for the horizontal transport of use and / or waste parts 10, 9.
It goes without saying that instead of the further conveyor belt 30, another suitable transport system can also be configured that takes over processed substrate sheets 1 or panels 10 and / or waste parts 9 from the conveyor belt 29.

Instead of the further conveyor belt 30, a container for receiving waste parts can also be arranged under the conveyor belt 30.
In addition to the conveyor belt 29, a further transport system 76 can also be assigned to the transport cylinder 3 directly, that is, forming a transfer area or transfer point between the transport cylinder 3 and the further transport system for processed substrate sheets 1 or panels 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or chain conveyor system with gripper bridges or a conveyor belt.
The mode of operation of an embodiment as preferably shown by the Fig. 11 or Fig. 12 . illustrated can be described as follows. The illustrated embodiment of the device for treating substrates is preferably part of a sheet-fed printing machine. The sheet-fed printing press can comprise one or more printing units. The in Fig. 11 or Fig. 12 . The illustrated embodiment has two processing cylinders between which the substrate 1 can be inserted, the substrate 1 being processed as it passes through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools that work in the cylinder gap. One of the processing cylinders is in Fig. 11 or Fig. 12 . shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 1 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, the processed, especially cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to this via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is at the points which he acts on benefit 10 provided with depressions. On the one hand, openings are made in the area of the panels 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panels 10 being covered by the elevator 5, that is to say closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, that is to say closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or precisely at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which the benefits 10 on the outer surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the items 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the break-out cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The remaining webs that form the waste parts 9 connect with the frame or with good parts 10, torn. Preferably at day point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9 even at day point A or immediately thereafter. When the respective benefits 10 reach the transfer point or transfer area C between the transport cylinder 3 and the transport belt 29, the first air supply means 14 are preferably deactivated. The negative pressure in the area of the first openings 12 is no longer applied and the panels 10 are no longer fixed and thus released. As a result of the negative pressure preferably applied to the conveyor belt 29 the panels 10 are lifted from the transport cylinder 3 at the transfer point or transfer area C, fixed on the underside of the conveyor belt 29 and transported away from it while hanging on it. The transfer of the panels 10 from the transport cylinder 3 to the conveyor belt 29 can be supported by applying an overpressure to the first openings 12. The supply of the first openings 12 is preferably switched from underpressure to overpressure when the first openings in the area of the respective panel 10 reach the transfer point or transfer area C. The benefits 10 can preferably be transported away with the further conveyor belt 30. To this end, the conveyor belt 29 conveys the items 10 to the further conveyor belt 30 and transfers the items 10 to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the items under the effect of gravity or by additional suction on the further conveyor belt 30 can be fixed on this and transported away by this. When the waste parts 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This releases the waste parts 9 or actively rejects the waste parts 9, which can be received by a waste container. In the area of the release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.
The further operation of an embodiment as it is preferably carried out by the Fig. 11 or Fig. 12 . illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, the processed, especially cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and is connected to it via so-called residual webs Waste parts 9 and use 10. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is provided with depressions at the points where it acts on the benefit 10. On the one hand, openings are made in the area of the panels 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panels 10 being covered by the elevator 5, that is to say closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, that is to say closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or precisely at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which the benefits 10 on the outer surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the items 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the break-out cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The remaining webs that form the waste parts 9 connect with the frame or with good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings which correspond to the third openings 32 of the stripping cylinder 4. The openings are formed in the area of the elevator 5 in which it is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force that lifts the panels 10 from the surface of the transport cylinder 3 is developed. The negative pressure at the third openings 32 of the break-out cylinder 4 is deactivated as soon as it exceeds the area of the Tangent point B have left again or a few degrees, in particular 10 degrees, then. The negative pressure applied to the first openings 12 is preferably deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective panel 10 is briefly lifted from the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few degrees, in particular 10 degrees of the rotational movement of the transport cylinder 3. This measure additionally supports the separation of utility 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at day point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9 even at day point A or immediately thereafter. When the respective benefits 10 reach the transfer point or transfer area C between the transport cylinder 3 and the transport belt 29, the first air supply means 14 are preferably deactivated. The negative pressure in the area of the first openings 12 is no longer applied and the panels 10 are no longer fixed and thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the panels 10 are lifted from the transport cylinder 3 at the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away from it while hanging thereon. The transfer of the panels 10 from the transport cylinder 3 to the conveyor belt 29 can be supported by applying an overpressure to the first openings 12. The supply of the first openings 12 is preferably switched from underpressure to overpressure when the first openings in the area of the respective panel 10 reach the transfer point or transfer area C. The benefits 10 can preferably be transported away with the further conveyor belt 30. For this purpose, the conveyor belt 29 promotes the benefits 10 to the next Conveyor belt 30 and transfers the items 10 to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated so that the items are fixed on the conveyor belt 30 under the action of gravity or by additional suction on the conveyor belt 30 and transported away by it . When the waste parts 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This releases the waste parts 9 or actively rejects the waste parts 9, which can be received by a waste container. In the area of the release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.

Another mode of operation of an embodiment as it is preferred by the Fig. 11 or Fig. 12 . illustrated relates to the whole sheet processing or the whole sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 1 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, the processed, especially cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to it via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are made at the points in the elevator 5 at which first and / or second openings 12, 13 are formed. When the first and / or second openings 12, 13 have passed tangent point A as a result of the rotation of the transport cylinder 3, or precisely at tangent point A, the first and / or second air supply means 14, 15 at the first and / or second openings 12, 13 a negative pressure is applied, which only the benefits 10 or only the waste parts 9 or the benefits 10 and the waste parts 9 are fixed to the outer surface of the transport cylinder 3 or to the elevator 5. As a result of the further rotation of the transport cylinder 3, the benefits 10 and the waste parts 9 pass the tangent point B. Contacting the waste parts 9 or the benefits with other elements does not take place at the tangent point B. When the respective use 10 and the respective waste parts 9 reach the transfer point or transfer area C between the transport cylinder 3 and the transport belt 29, the first and / or second air supply means 14, 15 are preferably deactivated. The negative pressure in the area of the first and / or openings 12, 13 is no longer applied and the benefits 10 and the waste parts 9 are no longer fixed and thus released. The fixing of the front edges of the substrate sheet 1 by the gripper system 17 is also canceled at the transfer point or transfer area C. As a result of the negative pressure preferably applied to the conveyor belt 29, the panels 10 and the waste parts 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (whole sheets), are removed from the transport cylinder 3 at the transfer point or transfer area C lifted off, fixed on the underside of the conveyor belt 29 and transported away from it while hanging on it. The transfer of the use 10 and the waste parts 9 and the frame of the substrate sheet 1 including the front edges of the substrate sheet 1 as a complete sheet from the transport cylinder 3 to the conveyor belt 29 can be supported by applying an overpressure to the first and / or second openings 12, 13. The supply to the first and / or second openings 12, 13 is preferably switched from underpressure to overpressure when the first and / or second openings 12, 13 reach the transfer point or transfer area C.

The complete sheets can preferably be transported away with the further conveyor belt 30. For this purpose, the conveyor belt 29 conveys the whole sheets to the further conveyor belt 30 and transfers the whole sheets to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the whole sheets under the action of gravity or by additional Suction on the further conveyor belt 30 can be fixed on this and transported away by this.
According to another preferred embodiment with stripping cylinder 4, a circulating conveyor belt 29 is assigned to the stripping cylinder, such as in particular from Fig. 13 can be seen. The transport belt 29 is preferably arranged above the transport cylinder 3. The conveyor belt 29 is assigned to the stripping cylinder 4, preferably forming a transfer point 38 or transfer area. Further preferably, the conveyor belt 29 is arranged to wrap around the stripping cylinder 4 over part of the circumference, forming an angle of wrap. The transfer point 38 or the transfer area is particularly preferably designed in the 8 o'clock position of the stripping cylinder 4 and the stripping cylinder 4 is assigned to the transport cylinder 3 in the 12 o'clock position of the transport cylinder 3. The length of the conveyor belt 29 is determined by the arrangement of pulleys. The conveyor belt 29 preferably has a first conveyor area 39 which extends at least approximately tangentially to the break-out cylinder 4. More preferably, the first transport area 39 is inclined at an angle between 30 and 60 degrees with respect to the horizontal. The conveyor belt 29 preferably has a second conveyor area 40 which runs at least approximately horizontally, in particular precisely horizontally. In particular, the transport belt 29 is a suction belt and the first transport area 39 is an area in which suction air is applied to the transport belt 29. The conveyor belt 29 has the particular function of taking over processed substrate sheets 1, waste parts 9 or benefits 10 at the transfer point 38 or transfer area between the conveyor belt 29 and the stripping cylinder 4 from the stripping cylinder 4 and transporting them further. Another transport system, for example in the form of a further transport belt 30, can be connected to the transport belt 29. An overlap area is preferably formed between the conveyor belt 29 and the further conveyor belt 30, in which the processed substrate sheets 1 or panels 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30. It goes without saying that instead of further Conveyor belt 30, another suitable conveying system can also be configured that accepts processed substrate sheets 1 or panels 10 and / or waste parts 9 from the conveyor belt 29. In addition to the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 3, that is, forming a transfer area or transfer point between the transport cylinder 3 and the further transport system 76 for processed substrate sheets 1 or panels 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or chain conveyor system with gripper bridges or a conveyor belt. The break-out cylinder 5 preferably has third openings 32 and third air supply means for supplying the third openings 32 with air. The third air supply means can preferably be switched between a suction air supply and a blown air supply. In particular, the third air supply means are designed to switch between suction air supply and blown air supply depending on the angular position of the respectively supplied third openings 32. The third air supply means are also preferably designed to switch the air supply to the third openings 32 from suction air supply to blown air supply when the respective third openings 32 reach a third release point by rotating the stripping cylinder 4 around its axis of rotation, in particular the transfer point or transfer area between the stripping cylinder 4 and conveyor belt 29 The third openings 32 can be designed in the form of grooves or holes. The third air supply means preferably comprise a rotary slide valve or a rotary inlet, it being possible for the at least one rotary slide valve or the at least one rotary inlet to be formed on the end face of the breakaway cylinder 4. Like the transport cylinder 3, the break-out cylinder 4 preferably has means for fixing an exchangeable elevator 5. The means for fixing are preferably designed as clamping grippers. With them, a respective elevator 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the elevator 5 are preferably by means of the clamping element front edge 22 and that is correlative with this with the formation of a clamping gap cooperating further clamping element 24 is formed. The front edge 22 of the clamping element is mounted on the base body of the stripping cylinder 4. The further clamping element 24 can in particular be formed as a leaf spring package. An adjusting element 25, preferably designed as a pneumatic muscle, is arranged adjacent to the further clamping element 24. The adjusting element is preferably connected to an air supply with which an overpressure can be applied to the adjusting element 25. The rear edge of the elevator 5 can be fixed between a clamping element rear edge 47 and a further clamping element rear edge 48, which together form a further clamping gap. The force required for closing the rear edge clamping gripper is applied by a rotatable tensioning shaft 50 which acts on the rear edge 47 clamping element via a toggle lever 51.
Further preferred details of the stripping cylinder 4 are shown in FIG Figure 10 and the associated description, to which reference is made in connection with the exemplary embodiment described. An elevator 5 with openings is preferably fixed on the stripping cylinder 4. The perforations in the elevator 5 of the stripping cylinder 4 correspond to the third openings 32 of the stripping cylinder 4. The perforations are preferably formed in the area of the elevator 5, in which it is not raised and interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force that lifts the panels 10 from the surface of the transport cylinder 3 is developed.
A preferred mode of operation of an embodiment as it is preferred by the Fig. 13 illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3 cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to this via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is at the points where it acts on the panel 10 with depressions Mistake. Breakthroughs are preferably made in the area of the panels 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panels 10 being covered by the elevator 5, that is to say closed. On the other hand, openings are preferably also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, i.e. closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or precisely at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which the benefits 10 on the outer surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3, the items 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the break-out cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The remaining webs that form the waste parts 9 connect with the frame or with good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings which correspond to the third openings 32 of the stripping cylinder 4. The openings are preferably formed in the area of the elevator 5 in which it is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective benefit 10 at the tangent point B or immediately in front of it, a negative pressure is applied to them. As a result This negative pressure develops a force that lifts the panels 10 from the surface of the transport cylinder 3. The negative pressure applied to the first openings 12 of the transport cylinder 3 is preferably deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective benefit 10 is lifted off the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder. The negative pressure applied to the second openings 13 is preferably maintained when the respective second openings 13 pass the tangent point B. As a result, the waste parts 9 are held on the surface of the transport cylinder 4 and transported past the tangent point B, while the items 10 are transferred from the transport cylinder 3 to the stripping cylinder 4 at the tangent point B. As a result of its rotation, the stripping cylinder 4 transports the items 10 fixed by negative pressure further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 4 and conveyor belt 29. At the transfer point or transfer area E of the stripping cylinder 4 and conveyor belt 29, a suction effect is preferably exerted on the side of the panel 10 facing away from the stripping cylinder 4 by the conveyor belt 29, which is preferably designed as a suction belt. When the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is also deactivated. An overpressure can preferably be built up at the third openings 32 following the deactivation of the negative pressure. As a result of the force effects described, the respective panels 10 in the transfer point or transfer area E are transferred from the stripping cylinder 4 to the conveyor belt 29. The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and preferably transports the copies 10 to a stacking device or storage device, not shown. After passing the transfer point or transfer area E through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 enter tangent point B again. Preferably at day point B, the second A vacuum is applied to the air supply means 15 at the second openings 13 in the area of the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9 even at day point A or immediately thereafter. When the waste parts 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This releases the waste parts 9 or actively rejects the waste parts 9, which can be received by a waste container. In the area of the release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.
Another mode of operation of an embodiment as it is preferred by the Fig. 13 . illustrated relates to the whole sheet processing or the whole sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 1 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3, the processed, especially cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to it via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are made at the points in the elevator 5 at which first and / or second openings 12, 13 are formed. When the first and / or second openings 12, 13 have passed tangent point A as a result of the rotation of the transport cylinder 3, or precisely at tangent point A, the first and / or second air supply means 14, 15 at the first and / or second openings 12, 13 a negative pressure is applied, which only the benefits 10 or only the waste parts 9 or the benefits 10 and the waste parts 9 are fixed to the outer surface of the transport cylinder 3 or to the elevator 5. When the respective use 10 and the respective waste parts 9 reach the tangent point B as a result of the further rotation of the transport cylinder 3, the first and / or second air supply means 14, 15 are preferably deactivated. The negative pressure in the area of the first and / or openings 12, 13 is no longer applied and the benefits 10 and the waste parts 9 are no longer fixed and thus released. The fixing of the front edges of the substrate sheet 1 by the gripper system 17 is also canceled at the tangent point B. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective benefit 10 at the tangent point B or immediately in front of it, a negative pressure is applied to them. As a result of this negative pressure, a force that lifts the panels 10 from the surface of the transport cylinder 3 is developed. The negative pressure applied to the first and / or second openings 12, 13 of the transport cylinder 3 is preferably deactivated when the respective first and / or second openings 12, 13 are in the area of the tangent point B. As a result of the negative pressure preferably applied to the third openings 32, the panels 10 and the waste parts 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (whole sheet), are at the tangent point B of the transport cylinder 3 lifted off and transferred to the stripping cylinder 4. The transfer of the use 10 and the waste parts 9 and the frame of the substrate sheet 1 including the front edges of the substrate sheet 1 as a full sheet from the transport cylinder 3 to the stripping cylinder 4 can be supported by applying an overpressure to the first and / or second openings 12, 13. The supply of the first and / or second openings 12, 13 is preferably switched from negative pressure to positive pressure when the first and / or second openings 12, 13 reach the tangent point B. As a result of its rotation, the stripping cylinder 4 transports the whole sheets fixed by negative pressure further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 4 and conveyor belt 29. In the transfer point or transfer area E of stripping cylinders 4 and Conveyor belt 29, preferably a suction effect is exerted on the side of the whole sheet facing away from the breaking cylinder 4 by the conveyor belt 29, which is preferably designed as a suction belt. When the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is also deactivated. An overpressure can preferably be built up at the third openings 32 following the deactivation of the negative pressure. As a result of the force effects described, the whole sheets are transferred from the stripping cylinder 4 to the conveyor belt 29 at the transfer point or transfer area E. The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and preferably transports the whole sheets to a stacking device or storage device, not shown. After passing the transfer point or transfer area E through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 enter tangent point B again.
According to another preferred embodiment with or without a break-out cylinder 4, a peeling device 31 (also called a peeling device) is assigned to the transport cylinder 3, such as in particular from Fig. 14 can be seen. The peeling device 31 preferably has a support surface which extends in the direction of a virtual tangent applied to the transport cylinder 3. The support surface can be aligned horizontally. The peeling device 31 is further preferably assigned a circulating conveyor belt 29 which can be designed as a suction belt circulating over deflection rollers. The peeling device 31 is assigned to the transport cylinder 3 preferably in its 12 o'clock position or, viewed in the direction of rotation of the transport cylinder 3, immediately adjacent to its 12 o'clock position. The transport belt 29 preferably has a transport area 37 inclined horizontally or at an angle of less than 10 degrees with respect to the horizontal. According to a preferred embodiment, the support surface formed on the peeling device 31 and the transport area 37 lie in one and the same virtual plane. Further Preferably, the support surface and the transport area 37 extend in the direction of a virtual tangent applied to the transport cylinder 3.
The transport cylinder 3 and the optional break-out cylinder 4 can be designed according to those embodiments of the transport cylinder 3 and break-out cylinder 4, as they are in particular in connection with the objects according to FIG Figures 9 to 13 have already been described.
The peeling device 31 has in particular the function of processed substrate sheets 1, waste parts 9 or panels 10 which are lifted off the surface of the transport cylinder 3 or the surface of the elevator 5 assigned to it with the help of the peeling device 31 and fed to the conveyor belt 29, which transports them away. Another transport system, for example in the form of a further transport belt 30, can be connected to the transport belt 29. An overlap area is preferably formed between the conveyor belt 29 and the further conveyor belt 30 in which the processed substrate sheet 1 or panels 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30.
It goes without saying that instead of the further conveyor belt 30, another suitable transport system can also be formed which takes over the processed substrate sheet 1 or panels 10 and / or waste parts 9 from the conveyor belt 29.
Instead of the further conveyor belt 30, a container for receiving waste parts 9 can also be arranged under the conveyor belt 29.
In addition to the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 3, that is, forming a transfer area or transfer point between the transport cylinder 3 and the further transport system 76 for processed substrate sheets 1 or panels 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or chain conveyor system with gripper bridges or a conveyor belt.
The mode of operation of an embodiment as preferably shown by the Fig. 14 illustrated can be described as follows. The illustrated embodiment the device for treating substrates 1 is preferably part of a sheet-fed printing machine. The sheet-fed printing press can comprise one or more printing units 6. The in Fig. 14 . Two processing cylinders are arranged upstream of the illustrated embodiment, between which the substrate 1 can be inserted, the substrate 1 being processed as it passes through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools that act in the cylinder gap. One of the processing cylinders is in Fig. 14 . shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 1 at tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3 cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to this via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is at the points where it acts on the panel 10 with depressions Mistake. On the one hand, openings are made in the area of the panels 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panels 10 being covered by the elevator 5, that is to say closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, that is to say closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or precisely at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which the benefits 10 on the outer surface of the transport cylinder 3 or on the elevator 5 fixed. As a result of the further rotation of the transport cylinder 3 achieve the through Use 10 and waste parts 9 fixed the tangent point B, which is formed between transport cylinder 3 and stripping cylinder 4, under vacuum. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The remaining webs that form the waste parts 9 with the frame or with good parts (benefit) 10 connect, torn. Preferably at day point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9 even at day point A or immediately thereafter. As a result of the rotation of the transport cylinder 3, the copies 10 and the waste parts 9 are transported past the point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling device 31. Before the respective panels 10 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first air supply means 14 of the transport cylinder 3 are switched from a suction air supply to a blown air supply. The negative pressure in the area of the first openings 12 is reduced so that the panels 10 are no longer fixed and, to the extent that the overpressure builds up at the first openings 12, are repelled from the surface of the transport cylinder 3 or from its elevator 5. Thus, at least the front edges of the panels 10 viewed in the direction of rotation of the transport cylinder 3 protrude in the radial direction of the transport cylinder 3 beyond the peeling device 31. The peeling device 31 aims in the gap formed between the front edges of the panels 10 and the surface of the transport cylinder 3 or its elevator 5. As a result of the rotation of the transport cylinder 3, the panels 10 are pushed onto the support surface of the peeling device 31 until they are in the detection area of the conveyor belt 29, which causes the benefits 10 to be transported away. in the In contrast to the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. When the release point D is reached, the negative pressure applied to the second openings 13 is deactivated. In a preferred embodiment, an excess pressure can also be applied to the second openings 13 when the second openings 13 reach the area of the release point D. With the process steps mentioned, not only is the fixing of the waste parts 9 terminated when the release point D is reached, but preferably the lifting of the waste parts 9 is supported by pneumatic means in addition to the force of gravity. In the area of the release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.
Another mode of operation of an embodiment as it is preferred by the Fig. 14 illustrated relates to the whole sheet processing or the whole sheet inspection and will be described below. The sheet transport cylinder transfers a processed substrate sheet 1 at tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3 cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and scrap parts 9 and panels 10 connected to it via so-called residual webs. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings. The openings are made at the points in the elevator 5 at which first and / or second openings 12, 13 are formed. When the first and / or second openings 12, 13 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or are located exactly at the tangent point A, the first and / or second air supply means 14, 15 at the first and / or second openings 12, 13, a negative pressure is applied which fixes only the use 10 or only the waste parts 9 or the use 10 and the waste parts 9 on the lateral surface of the transport cylinder 3 or on the elevator 5. As a result of the further rotation of the transport cylinder 3, the benefits 10 and the waste parts 9 pass the tangent point B. The waste parts 9 or the benefits 10 do not come into contact with other elements at the tangent point B. The stripping cylinder 4 is parked by the transport cylinder 3. When the respective use 10 and the respective waste parts 9 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first and / or second air supply means 14, 15 are deactivated or preferably switched to blown air supply. The negative pressure in the area of the first and / or second openings 12, 13 is no longer applied and the panels 10 and the waste parts 9 and the frames of the substrate sheets 1 including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (whole sheet ), are no longer fixed and thus released at the transfer point F and preferably lifted in a targeted manner from the surface of the transport cylinder 3 or from the elevator 5. The fixing of the front edges of the substrate sheet 1 by the gripper system 17 is also canceled at the transfer point or transfer area C. As a result of the rotation of the transport cylinder 3, the whole sheets are then pushed over the support surface of the peeling device 31 until they reach the active area of the transport belt 29, from which they are transported away.
The mode of operation of an embodiment as preferably shown by the Fig. 15 illustrated can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 at tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder to the transport cylinder 3 cut substrate sheet 1 takes over. The substrate sheet 1 preferably comprises an edge and is connected to it via so-called residual webs Waste parts 9 and use 10. The transport cylinder 3 carries an elevator 5. The elevator 5 has openings and is provided with depressions at the points where it acts on the benefit 10. On the one hand, openings are made in the area of the panels 10 at the points in the elevator 5 at which first openings 12 are formed, the second openings 13 in the area of the panels 10 being covered by the elevator 5, that is to say closed. On the other hand, openings are also made in the area of the waste parts 9 at the points in the elevator 5 at which second openings 13 are formed, the first openings 12 in the area of the waste parts 9 being covered by the elevator 5, that is to say closed. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or are located exactly at the tangent point A, the first air supply means 14 apply a negative pressure to the first openings 12, which the benefits 10 on the outer surface of the transport cylinder 3 or fixed on the elevator 5. As a result of the further rotation of the transport cylinder 3, the items 10 fixed by the negative pressure and the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the break-out cylinder 4. At the tangent point B, the raised areas of the elevator 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the depressions of the elevator 5 fixed on the transport cylinder 3. The remaining webs that form the waste parts 9 connect with the frame or with good parts 10, torn. The elevator 5 fixed on the stripping cylinder 4 has openings which correspond to the third openings 32 of the stripping cylinder 4. The openings are formed in the area of the elevator 5 in which it is not raised or interacts with the panel 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and face a respective panel 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force that lifts the panels 10 from the surface of the transport cylinder 3 is developed. The negative pressure at the third openings 32 of the break-out cylinder 4 is deactivated as soon as it exceeds the area of the Tangent point B have left again or a few degrees, in particular 10 degrees, then. The negative pressure applied to the first openings 12 is preferably deactivated when the respective first openings 12 are in the area of the tangent point B. This ensures that the respective panel 10 is briefly lifted from the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few degrees, in particular 10 degrees of the rotational movement of the transport cylinder 3. This measure additionally supports the separation of utility 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at day point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As an alternative to this, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of the waste parts 9 even at day point A or immediately thereafter. As a result of the rotation of the transport cylinder 3, the copies 10 and the waste parts 9 are transported past the point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling device 31. Before the respective panels 10 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first air supply means 14 of the transport cylinder 3 are switched from a suction air supply to a blown air supply. The negative pressure in the area of the first openings 12 is reduced so that the panels 10 are no longer fixed and, to the extent that the overpressure builds up at the first openings 12, are repelled from the surface of the transport cylinder 3 or from its elevator 5. Thus, at least the front edges of the panels 10 viewed in the direction of rotation of the transport cylinder 3 protrude in the radial direction of the transport cylinder 3 beyond the peeling device 31. In the gap formed between the front edges of the benefit 10 and the surface of the transport cylinder 3 or by its elevator 5, the peeling device 31 aims. As a result of the rotation of the Transport cylinder 3, the panels 10 are pushed onto the support surface of the peeling device 31 until they reach the detection area of the conveyor belt 29, which causes the panels 10 to be transported away. In contrast to the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. When the release point D is reached, the negative pressure applied to the second openings 13 is deactivated. In a preferred embodiment, an excess pressure can also be applied to the second openings 13 when the second openings 13 reach the area of the release point D. With the process steps mentioned, not only is the fixing of the waste parts 9 terminated when the release point D is reached, but preferably the lifting of the waste parts 9 is supported by pneumatic means in addition to the force of gravity. In the area of the release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.
Instead of the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 3, that is, forming a transfer area or transfer point between the transport cylinder 3 and the further transport system 76 for processed substrate sheets 1 or panels 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or sheet guide system, in particular a chain conveyor system with gripper bridges, or a conveyor belt. An embodiment with a chain conveyor system with gripper bridges as part of the delivery 99 of a sheet-fed printing machine is shown in FIG Fig. 17 shown.
The chain conveyor system contains traction means which are moved via drive and deflection means and which drive gripping devices, in particular gripper bridges, for conveying substrates. The gripping devices have fixing members for taking over and fixing the sheet-like substrates 1. In particular, clamping and / or suction grippers can be used as fixing elements for gripping the substrate edges. In further training not shown additional gripping devices are provided for the substrate trailing edges. The sheet conveyor system, designed here as a chain conveyor system, contains chains placed over chain wheels and driven by them, guided in laterally arranged guide rails, not shown, on which gripper bridges for transporting the substrates 1 are arranged. The substrates 1 are conveyed by the gripper bridges in the transport direction to the delivery stack stored on, for example, a pallet or some other type of transport support. The gripper bridges preferably contain leading edge clamping grippers which have gripper fingers which interact with gripper bridges and which are arranged spaced apart from one another on a gripper shaft and can be controlled by the latter.
A substrate guide device and, for example, a dryer are provided in the display 99 for safe transport of the substrates 1 held by the gripper bridges. The substrate guide device has substrate guide plates which face the gripper bridges and which are provided with blown air nozzles and extend over the width of the machine. Blow boxes, via which the blown air nozzles are supplied with blown air, are arranged below the substrate guide plate, so that a support air cushion is formed between the substrate guide plate and the substrates 1 transported by the gripper bridges. A coolant circuit can be integrated in order to be able to regulate the heating of the substrate guide plate in the area of the dryer. In order to avoid the substrates 1 sticking together on the display stack, a release agent application device, not further designated, is preferably provided in the area of the display 99, in particular a powder device, preferably combined with a device for sucking off the powder.

The elevator 5 is preferably fed by the action of gravity or, alternatively, driven by a motor or manually. When the rear edge of the elevator 5 has reached the clamping gap, the pneumatic muscle 25 is relaxed and the rear edge of the elevator 5 is thus fixed between the clamping jaw 22 and the cuff 24. The stripping cylinder 4 is then rotated clockwise by a motor. When the rear edge of the elevator 5 has moved under the pressure roller 61 through the rotation of the stripping cylinder 4, the linear drive 65 is activated. The linear drive 65 pivots the pressure lever 63 until the pressure roller 61 rests against the elevator 5 and presses it against the outer surface of the stripping cylinder 4. The stripping cylinder 4 is then rotated further in a clockwise direction by a motor, while in the area of influence of the pressure roller 61 the elevator 5 is pressed onto the outer surface of the stripping cylinder 4 until the front edge of the elevator 5 reaches the clamping gap formed between the clamping jaw 47 and the impact 48. When the front edge of the elevator 5 is inserted into the clamping gap, the tensioning shaft 50 is rotated and the clamping gap is thus closed. The pressure roller 61 is then pivoted away. If the elevator 5 is to be removed from the stripping cylinder 4 again, the pressure roller 61 remains pivoted away from the stripping cylinder 4. Either that The front edge or the rear edge of the elevator 5 is released by the stripping cylinder 4 and the stripping cylinder 4 then rotates, so that the elevator 5 is conveyed again in the direction of the store 73.
